Yesterday I worked on the top opening cylinders on my Wife's SLK230 and was able to get it to go up and down by filling the pump with hydraulic fluid. There is a leak in the passenger side top cylinder so there just was not enough fluid to make the top go up and down. Of course this meant I had to make a trip to the Mercedes dealer in Columbus, OH as that is the only hydraulic fluid I have found that will work. The seals still need replaced in the cylinder but that can wait until after we go on the Fall Foliage Tour in Coshocton, OH, next weekend.
So that left Sunday open to work on installing the new ignition switch and removing the instrument cluster. The steering column was dropped and the new ignition switch went in smoothly. Next the screws were removed and the instrument cluster was removed. Upon inspection, the ground wire had come off of the small dc-dc converter for the 12 volt meter, so that is why it had quit working. It is my hope that the new circuit board will solve the right side instrument cluster lights not working and will also fix the trip counter, that currently is not working. I want to find either a plug or a circuit board with a plug for the 12 volt dc-dc converters, as soldering the wires to the small terminals is hit and miss at best.
